Thyroid Specialist in Surrey

Dr Mamta Joshi | Consultant Endocrinologist | Spire St Anthony's Hospital, Cheam
Written by Dr Mamta Joshi, MD, FRCP, Consultant Endocrinologist — reviewed  October 2026

Thyroid conditions are among the most common endocrine disorders in the UK, yet many patients spend years with symptoms that are inadequately investigated or managed without specialist input. If you are experiencing persistent fatigue, unexplained weight changes, sensitivity to temperature, or mood and cognitive difficulties that have not been fully explained, a specialist thyroid assessment may help clarify what is happening and what options are available to you.

​

​

Dr Mamta Joshi is a Consultant Endocrinologist with over a decade of clinical experience, practising at Spire St Anthony's Hospital in Cheam, Surrey. She sees patients from across Surrey and South London for private thyroid consultations, providing specialist-level investigation and management for the full range of thyroid conditions.

​

What conditions does this cover?

The thyroid is a small gland in the neck that produces hormones regulating metabolism, energy, temperature, and many other body systems. When it produces too little or too much hormone, or when the immune system attacks the gland, a wide range of symptoms can follow.

​

Dr Joshi's private thyroid consultations cover:

​

• Underactive thyroid (hypothyroidism): the thyroid does not produce enough hormone, which can lead to fatigue, weight gain, cold sensitivity, and cognitive slowing.

• Overactive thyroid (hyperthyroidism): the thyroid produces too much hormone, which can cause weight loss, palpitations, anxiety, and heat sensitivity.

• Hashimoto's thyroiditis: an autoimmune condition in which the immune system attacks the thyroid, the most common cause of hypothyroidism in the UK

• Graves' disease: an autoimmune condition causing hyperthyroidism.

• Thyroid nodules: lumps within the thyroid gland that require specialist assessment to determine whether further investigation is needed

• Thyroiditis: inflammation of the thyroid, including post-partum thyroiditis, post viral thyroiditis or caused by drugs.

Not all thyroid conditions present with obvious symptoms, and some patients are referred following an abnormal blood test result rather than specific complaints. A specialist consultation provides the full clinical picture regardless of how you have arrived at it.

​

Why patients seek a private thyroid specialist

​

Many patients seek a private thyroid consultation after finding that their concerns have been difficult to get fully investigated through existing routes.

Common reasons include:

• Test results falling within the normal reference range, but symptoms continuing to affect quality of life

• Wanting a more thorough investigation, including additional thyroid antibody or function tests that are not routinely offered

• Difficulty optimising treatment on standard therapy

• Managing an autoimmune thyroid condition alongside other health concerns

• Wanting a second opinion on a diagnosis or treatment plan

• Seeking specialist input during pregnancy or in the post-partum period

A private consultation with Dr Joshi provides dedicated time, a full clinical assessment, and specialist-level discussion of your results and the options available to you.

​

What to expect at your consultation?

​

Your first consultation with Dr Joshi will typically involve:

• A detailed review of your symptoms, medical history, and any previous thyroid tests or imaging

• A discussion of your concerns and what you are hoping to understand or address

• Consideration of appropriate further investigations: blood tests and, where clinically relevant, thyroid ultrasound

• A clear explanation of your results and what they mean in the context of your symptoms

• A discussion of the management options available, tailored to your individual situation

No treatment is prescribed without a full assessment. Dr Joshi's approach is to give you the information and the time you need to make informed decisions about your care.

​

Thyroid conditions and other health concerns

​

Thyroid function does not sit in isolation. It interacts with a range of other endocrine and metabolic processes, and managing thyroid conditions well sometimes means looking at a broader picture.

​

For example, thyroid dysfunction can affect weight, mood, and metabolic health. In women, it is not uncommon for thyroid conditions to present alongside or be mistaken for other hormonal concerns such as PCOS or perimenopausal symptoms.

​

As a Consultant Endocrinologist with specialist training across the full endocrine system, Dr Joshi is well placed to assess these interactions and provide a joined-up view when that is clinically relevant
